RAIL-SCRAPER. y

SPECIFICATION forming part of Letters Patent No. 565,454, dated August 11, 1896.

Application led October 28, 1895. Serial No- 56'7138. (N0 11106181.)

.To all whom t may concern:

Be it known that -I,WILLIAM GrrtUNow7 J r., a Citizen of the United States, and a resident of Bridgeport, in the county of Fairiield and State of Connecticut, have invented certain new and useful Improvements in Rail-Scrapers, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

My invention relates to improvements in rail-scrapers, and the obj ect thereof is to provide a simple device which can be easily and inexpensively constructed and quickly manipulated to bear more or less upon the rails.

Vth this and other ends in view the invention contemplates a rock-shaft suitably journaled in bearings beneath the car-truck, iiexible steel arms secured on the ends of said shaft and projecting forwardly, a piece of flat metal arranged between jaws on the ends of said arms, a leverrigidly connected to the shaft and adapted to rock the same, and a helical spring secured at one end to the shaft and at the other end to the car-truck and normally holding the plates in contact with the rails, all arranged and disposed in the manner described and claimed.

The invention consists also of certain details of construction and arrangements of parts, more fully set forth and claimed in the following specification.

In the accompanying drawings, Figure lis a side elevation of my improved scraper detached from the car, and Fig. 2 is a top plan view. p

In the practice of my invention I provide a rock-shaft A, which is journaled in bearings a in brackets a', or in the sides of the car-truck, as desired. On the outer ends of this shaft are rigidly secured the forwardlyprojecting arms B, which are made of flat flexible tempered steel plates, and in the ends of said arm are the angularly-disposed sockets l), formed by the parallel jaws b. These jaws b are Adirected inwardly and backwardly at an angle to the arms. so that the scraper-plates C held thereby will operate obliquely across the rails. f

The scraper-plates are made of metal, and

to one end of a rod d, which extends to a convenient place under the car-body, where it is connected with a bellcrank d. One arm of the bell-crank d' is connected with the lower end of a pull-rod d2, which projects up through an opening in the floor of the platform of the car and is provided with a shoulder d3, arranged to engage the edge of said opening, by means of which the parts are held in position.

On the upper side of one of the jaws b', I provide an eyelet b2, to which a chain b3 is attached for the purpose of supporting the device out of contact with the car-track.

At one end, or both ends, of the shaft A I provide a helical spring E, one end of which is fastened to the shaft and the other end to the car-truck or a hanger. The tendency of this spring is to hold the scraper-plates in Contact with the rails.

In operation the chain b3 or the pull-rod d2 is disengaged to permit the springs E to force the scraper-plates against the rails, and when it is desired to withdraw the scraper-plates from the rails the pull-cord is operated again to rock the shaft A.

I am aware that changes in the form and proportion of the parts of my invention and the details of construction may be made without departing from the spirit of my inven- IOO in the end of said rod extending rearwardly and provided on their free end with parallel jaws arranged at an angle to the rod, scraperplates secured beneath the said jaws, and a helical spring normally maintaining said plates and ear-tracks in contact with the rails, substantially as described.

In a scraper, the combination with a rod, arms on the ends of said rod extending rear- Wardly7 parallel jaws on the free end of said rods arranged at an angle to the rod and in the sockets, scraper-plates secured in said sockets, a helical spring on the rod normally maintaining said scraper in contact with the rails and a lever secured to the rod and passing through the ear-truck and adapted to rock said rod, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two Witnesses, this 30th day olf July, 1895.
